ROBERT MCSHANE, OF BROOKLYN, NEW YORK.

GONG-BELL.

SPECIFICATION forming part of Letters Patent No. 258,787, dated May 30, 1882. Q Application filed February 27, 1832. (No model.)

To all whom it may concern:

Be it known that 1, ROBERT MGSHANE, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Gong-Bells, of which the following is a full, clear, and exact .description.

The object of my invention is to furnish a double-stroke gong-bell that can be readily changed for right or left hand connections, as required by the location of use; and it consists in an operating-lever trip and pivoted hammer, combined and arranged as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure l is a face view of my improved bell mechanism arranged for right-hand connections, and Fig. 2 is a similar view, showing the parts arranged for left-hand connections, the gong being removed in both figures.

A is the supporting-plate, provided with a B is the hammer, pivoted on a stud, b, and arranged for striking on the outside of the gong. U is the hammer-spring. I) is the operatinglever, hung on a stud, c. E is a spring connected from lever D to a stud, d, on the plate, and F is a trip or dog pivoted on a stud, c, between the inner end of lever D and the hammer B. fj'are stops limiting the movement of the lever.

The trip or dog F is formed with three arms or projections, g g 9 one of which, g, projects for engagement by the end of lever 1), while the projections g g are normally in contact with the hammer-arm; but in case it is desired to give only one stroke one arm or projection, g or g will be removed.

At h in Fig.1 right-hand connections are shown at the outer end of the operating-lever, and in that case the spring E, as shown, engages a lug or connection, 2', near the inner end of the lever.

. To arrange the bell left-handed,the spring E is simply to be disconnected from lug i and connected to a lug, i, that is on the lever at the other side of the fulcrum-stud o. The inner end of the lever is thereby carried to the reverse side of the dog, as shown in Fig. 2.

The first movement of the operating-lever turns the dog and raises the hammer until the lever end clears, when the trip is released and the hammer is brought down with a blow upon the bell. The return movement is given by spring E, which, by carrying the lever back to the first position, moves the'dog and causes the second stroke of the bell. The movement is easy, and but slight power is required on account of the double leverage. I

Having thus described my invention, I claim as new and desire to secure by Letters Patent- In a door-bell, the combination, with the hammer B and the spring 0, of the lever D, provided with the lugs 73 i, the spring E, and the dog F, provided with the projections g g 9 substantially as and for the purpose set forth.
